ABSTRACT:
A molded plastic carton end includes a thin face panel reinforced by molded ribs and bounded on four sides by rim sections each comprising a plurality of parallel walls abutting against a face member with closely spaced cross members to add additional stiffness and resistance to crushing. The multiple walls also provide a plurality of parallel layers to receive and hold nails for attaching side, top and bottom members to complete the carton. The walls intersect at the corners, thus forming a large number of individual box sections at each corner, making the corners of the carton end very resistant to deformation. A number of plastic materials and fillers may be used including polyethylene filled with wood and/or a limited amount of a blowing agent.
